IMPROVEMENT IN MOUSlNG-HOOKS Specification forming part of LettersPatent No. 175,353, dated March 28, 1876; application filed November 19,1875.

To all whom it may concern Be it known that I, NELs E. JOHNSEN. ofChelsea, in the county of Sufiolk and State of Massachusetts, haveinvented a new and useful Improvement in Mousing Hooks, of which thefollowing is a specification Figure -l is a side view of my improvedmousing-hook, part being broken away to show the construction. Fig. 2 isan end view of one part of the same. Fig. 3 is a front view of one partof the same.

Similar letters of reference indicate corresponding parts.

The object of this invention is to furnish an improved mousing hook,simple in construction, easily applied, and safe in use, not beingliable to become accidentally detached.

The invention consists in the tongued notches formed in the parts of thehook at their shoulders, and the grooved shoulders or projections formedupon said parts at their points, to adapt the parts of the hook tointerlock with each other; in the combination of a spring-key'with themortised elongated shanks ot' the parts of the hook, and in thecombination of the block with the ends of the pear-shaped thimble, ashereinafter, fully described.

The mousing-hook A is formed of two main parts, the forward parts orhooks a of which are halved and tapered to overlap and lit upon eachother. At the shoulders of the books a are formed notches M, the forwardsides of which are provided with tongues a as shown in Figs. 1 and 2.Upon the ends of the hooks a are formed shoulders a, in which are formedgrooves a to receive the tongues a3. The tongues a and the grooves aextend only halfway across the hooks a so that they may serve as locksand as stops to keep the parts in place upon each other. The shanks a ofthe hook are elongated, and have a mortise formed through them toreceive the spring-key B, by which they are secured to each other. Inthe outer ends of the shanks a are formed large eyes a to receive therope c and the thimble D.

The thilnble D is made pear-shaped, and has a groove in its outer sideto receive the eye ofithe rope G. d is a small block interposed betweenthe ends of the thimble'D, to support said ends, and thus allow thethimble to be made shorter than would otherwise be necessary, to form acavity of the required size.

To open the hook the spring-key B is withdrawn, and the eyes a slippedaround upon one of the armsof the thimble D, which allows the parts ofthe hook to be drawn apart.

Having thus described my invention, 1 claim as new and desire to secureby Letters Patent 1. Amousing-hook provided with hooks a, notches atongues a shoulders a, and grooves a construcced and arranged as and forthe purpose specified. I

2. The combiuationrof a spring-key, B, with the mortised elongatedshanks a of the parts of the hook A, substantially as herein shown anddescribed.

3. The combination of the block d with the ends of the pear-shapedthimble D, substantially as herein shown and described.
